Y '0 all 10/1077} it may concern:

c it known that I. Axnmcas O'r'r, a subject of the Emperor of Germany. residing at ()berkassel-Siegkreis. Germany. have invented a certain Stereotype-Matrix Machine, of which the following is a specification.

he present invention relates to a machine in which stereotype matrices are made by means of a type wheel which is operated through the medium of key-levers and which works against a platen carried by a sliding carriage.

The invention consists in the provision of a carriage feeding mechanism which can be set for anydesired spacing of the letters and characters. In. the second place an electromagnet with adjustable core is provided which operates the type in the first place wheel and which is energized by the de prcssion of the key-levers. Several 1mprovcments are also introduced in connec tion with the carriage. the platen, and the guide for the matrix material.

In the accompanying drawings the inven tion is illustrated, Figure 1 representing a side view of the machine, in section on the hue A A of Fig. and Fig. 9, a plan of the machine. the c tted for the sake of clearn i machine frame 1 contains a guide-way 3 for the carriage i which has at each end a bracket 5 for the reccptimi of the shafts of the platen 6 and two guide-rollers 7 and 8. "he carriage holds a trough 10 for moistening he matrixanaterial 9 by a roller '11 through the liquid and then led to the rollers 7 and 8. To the underside of the carriage a toothed rack 12 is secured which normally meshes with a worm 13 for feeding the carriage. The shaft of the worm. 13 is rotatably held at one end in a U-shaped shackle 19 whose ends are s shaft 15 that it an tuin'about the latter. he free end of the worm shaft is guided vertically between two ln'ackets 22 and supported on a wedge 23 which is slidably arranged in slots made in said brackets. A bell-crank lever 24, having an operating knob 25, has one arm pivoted to the wedge 23 for sliding the latter longitudinally with in tl'iebrackets. As the wedge is moved in .the. direction of its thicker end, it causes the supported end of the Worm shaft to descend the Worm from the rack 12 and allow the carriage to be moved freely. 1e Worm is driven by a beve gear 21 arriage being omi shafts H which is guided 0 connected to a Specification of Letters Patent.

A spring tends to hold the type wheel away from the platen 6, The arm 39 has a rearward. extension l6 which forms an armature for the core 44: of the magnet l3. The electric circuit of themagnet 43 is closed by means of the key levers '27 each one of which carries for this pur-- pose a contact pression of the lever, to abut against and connect electrically a pair of studs 50. One stud of each pair is connected to a bar &6 and the other to a car 4L7. These bars are insulated and s1 )ortecl by "ings l8 on brackets s9. ectric leads connect the bars l6 and 4:7 with the magnet as well as with an electric source. i l hen, at the connection of pair of studs 50, the circuit of the magnet is closed, the armature l0 is attracted and the arm 39 suddenly turned so as to apply the type wheel 36 to the platen. The core 4%, which limits the movement of the arm 39, is held by a screw so that it can be ad usted for causing the wheel 36 to make more or less deep impressions in the material 9.
